You have to go to their actual updates. They're up to v59 (part 5). Also, after this section in the image, I get an error. And if I continue to play after choosing ignore, it will give me more errors later.
I know the issue. The issue is that the patch listed on Itchio does not have an updated Character identifier for the Great-Grandmother.
Opening the file with notepad and adding the following line to it will solve the problem.
define gna = (_("great grandmother"))
